past couple of weeks I've been occasionally having my internet stop working for a few minutes; didnt think too much of it, but over the last couple days, it's gotten pretty frequent. According to my modem's logs, since early this morning (logs only go back so far) every ~90 minutes or so I've been getting these errors:
| Jan 15 05:28:05 2021 | Critical (3) | SYNC Timing Synchronization failure - Loss of Sync |
| Jan 15 05:28:10 2021 | Warning (5) | Lost MDD Timeout |
| Jan 15 05:28:50 2021 | Critical (3) | Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out |
| Jan 15 05:30:23 2021 | Critical (3) | No Ranging Response received - T3 time-out |
| Jan 15 05:31:09 2021 | Critical (3) | Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out |
| Jan 15 05:31:44 2021 | Warning (5) | MIMO Event MIMO: Stored MIMO=-1 post cfg file MIMO=-1 |
these repeat, I've contacted xfinity support through chat, and have had them look at my account, done all their recommended stuff (basically just resetting the modem over and over), and according to them, everything looks good...and then 90 mins later, same errors and I talk to support again.
so that happened a few times, and now I've got a tech coming next week, so my request here is: what can I do, info can I provide to make this a "one and done" trip for the tech?
other info that is probably? useful

also, I've had an ip ping going for hours, and every time internet drops I get "request timed out", and all the downstream stuff in modem info is 0 (upstream doesnt change/is fine) before it auto-resets. lets see, coax is the one I got from xfinity, runs direct to my modem, then to router, then ethernet to pc/ps4 (currently skipping the router and direct from modem to PC for troubleshooting, no changes). ipconfig/all shows the lease as: "Lease Obtained. . . . . . . . . . : Friday, January 15, 2021 10:13:29 AM
Lease Expires . . . . . . . . . . : Tuesday, January 19, 2021 9:10:36 AM" and I'm in an apartment, so I dont have access to anything outside thx for reading, if anyone wants more info, lemme know; I appreciate any advice |
